In a parallel where superheroes are going to exist Aliens contact the Earth in 1889. The aliens see a rapidly advancing species saddled with archaic governments. Which means they realize that next couple or so centuries of Earth's life are going to be seriously violent. However the aliens test certain human volunteers (they asked and plenty of Brits, Germans, Americans, French folks, and others said "Yes.") and discovered that soon, a couple of generations at most, people with paranormal powers would appear on the Earth, and in very high numbers. These Aliens aren't malicious or cruel, but they are profit motivated. They decide to stick around and take advantage of the coming crops of superbeings.

The Local Year is now 1942, the first waves of supers are here, and what a wildly mixed bunch. The aliens, deciding they preferred to with the democracies, have altered history seriously. FDR is vital and healthy, snow skiing, tennis, horseback riding. He's still the New Dealer, and with alien tech and advice, prosperity (Tech Level Eight prosperity) came quickly. Britain, has colonies on the moons of Jupiter and France is exploring a very Pulp Sci Fi Venus, while Wiemar Germany (Hitler paints postcards in Vienna) takes the lead in exploring the lost civilizations of Mars. China is enjoying stable peaceful prosperity and is only now working on it's space fleets.

However, this world of prosperity, superheroes, and space explorers, is not truly placid. Japan, Soviet Russia,Franco's Spain, and other hostile states have been contacted by aliens in competition with the first set of aliens. These new aliens want slaves. If Japan, Russia, and Spain, would like godlike power and wealth, these aliens would give them that in exchange for the peoples living in the lands these powers covet. Stalin has already said yes. Can Tojo and Franco be far behind?
